The 37-year-old, who is already mum to Liam, 4, and Stella, 2, has admitted that despite her third pregnancy being a shock, it made her want a fourth child.

“When I found out about baby number three, I thought that would be the last one,” Tori revealed. “But we really want to have a fourth. It’s really funny, it just clicked – we want more!” she explained.

Like other celeb mums-to-be, such as Myleene Klass and Celine Dion, Tori revealed that she’s been suffering from severe morning sickness. “I was really, really sick the first three months,” admitted Tori. “It was much worse than during my other pregnancies.”
